SPECIFICATION forming part of Letters Patent No. 740,689, dated October 6, 1903.

drawings, and to the characters of reference marked thereon, which form a part of this specification.

It is well known that in filling bottles with the aid of ordinary funnels the liquid almost invariably overflows from the bottle.

The present invention relates to a funnel in which the passage of the liquid from the funnel into the bottle is automatically closed requiring any special attention on the part ofthe operator. Such a funnel is illustrated in the accompanying drawings, in which- Figure 1 is a central vertical section through the funnel. Fig. 2 is a detail plan view showing the support for the air-tube, and Fig. 3 is a sectional detail showing the bottom of the funnel with the valve closed.

The funnel 1- is provided round its neck with a rubber stopper 3, which enables the funnel to be placed into the bottle so that no air shall escape round the neck. In the center of the funnel a small pipe 4 is arranged, the lower end of which is open and carries a valve,said valve being preferably constituted, as shown in the drawings, byarubber disk 6, a semispherical cap or part 7, arranged above it and having the shape of a cup or a cone, and another part or cup, 8, of the same shape below it. When the valve is closed, the upper cup 7 fits lightly into the lower end of the funnel, Fig. 3, the result being that the valve-disk always completely closes the orifice of the funnel, the lower cup 8 causing the disk to funnel, thus insuring a tight joint.

The pipe 4 is guided in a metal band or support 9, arranged or secured across the interior of the funnel, its downward movement being limited by a stop 10. At the top of the pipe is a detachable bent wire handle 11, havreference being bad to the accompanying as soon as the bottle has been filled without pipe and surrounds it.

press firmly against the lower edge of the ing spring ends 12 bent at right angles, the ends 12 engaging in corresponding holes in the pipe, and thus holding the handle fast. By pressing the points inward the handle can easily be removed. pipe 4 to be easily removed for the purpose of cleaning the funnel, the metal band 9 is provided with a slot 13,through which the stop 10 can pass. A disk 14 is loosely mounted above the metal band and is also provided with a slot 15 for the passage of the stop 10 and is intended to prevent normally the stop from passing through the slot 13. This, however, can be prevented in any other manner.

The working of the funnel according to this invention is as follows: The funnel is placed.

into the bottle and held with its rubber stopper slightly pressed into the bottle-neck, so as to secure an air-tight joint between the bottle and the funnel. The bottle can now '55 In order to enable the be filled. The air from the bottle escapes through the pipe 4 until theliquid reaches the level of the lower end or orifice of the At that moment the further escape of the air still contained in the space A is impossible, and further discharge of liquid from the-funnel into the bottle is accordingly prevented. The funnel is then taken by the handle 11 and lifted out. During this operation the valve-disk 6 keeps the lower orifice of the funnel closed, so that the liquid contained in the funnel cannot escape until the handle is released, and the said liquid can be discharged into some other vessel or bottle.

A further advantage of this device is that it can be easily attached to any ordinary funnel.

Having thus described the invention, what I claim as new is- 1. An automatically closing funnel provided with a rubber or other elastic stopper of conical shape round its neck and with an open pipe guided in a support in the funnel, and having its downward movement limited by suitable means, said pipe being provided at its lower end, which projects beyond the funnel-orifice, with a rubber or similar valvedisk arranged between two semispherical disks, substantially as described.

2. An automatically-closing funnel whose neck is provided with a conical rubber or other elastic stopper, a central open pipe, one the pipe, substantially as and for the purend projecting below the bottom end of the pose described. 10 funnel-neck and being provided with a valvei In testimony whereof I affix my signature disk, the end projecting above the funnel bein presence of two witnesses.
